abstract struct Int

Overview

Int is the base type of all integer types.

There are four signed integer types: Int8, Int16, Int32 and Int64,
being able to represent numbers of 8, 16, 32 and 64 bits respectively.
There are four unsigned integer types: UInt8, UInt16, UInt32 and UInt64.

An integer literal is an optional #+ or #- sign, followed by
a sequence of digits and underscores, optionally followed by a suffix.
If no suffix is present, the literal's type is the lowest between Int32, Int64 and UInt64
in which the number fits:
